Carnation plant named ‘Hilbeaolswee’

ABSTRACT

A new and distinct cultivar of Carnation plant named ‘Hilbeaolswee’, characterized by its compact, uniformly mounding and upright to broadly spreading plant habit; relatively small leaves; freely flowering habit; red-colored single flowers with white-colored centers and narrow margins; and good container and garden performance.

Botanical designation: Dianthus L.

Cultivar denomination: ‘HILBEAOLSWEE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus L., grown commercially as a container plant and hereinafter referred to by the name ‘Hilbeaolswee’.

The new Carnation plant is a product of a planned breeding program conducted by the Inventor in Miniami-Alps City, Yamanashi, Japan. The objective of the breeding program is to create new container Carnation plants with numerous attractive single-type flowers.

The new Carnation plant originated from a cross-pollination made by the Inventor in Miniami-Alps City, Yamanashi, Japan in June, 2010 of a proprietary selection of Dianthus L. identified as code number JP 02, not patented, as the female, or seed, parent with a proprietary selection of Dianthus L. identified as code number JP 15, not patented, as the male, or pollen, parent. The new Carnation plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Miniami-Alps City, Yamanashi, Japan in September, 2011.

Asexual reproduction of the new Carnation plant by terminal cuttings propagated in a controlled greenhouse environment in Miniami-Alps City, Yamanashi, Japan since October, 2011 has shown that the unique features of this new Carnation plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Carnation have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hilbeaolswee’. These characteristics in combination distinguish ‘Hilbeaolswee’ as a new and distinct Carnation plant:

-   -   1. Compact, uniformly mounding and upright to broadly spreading         plant habit.     -   2. Relatively small leaves.     -   3. Freely flowering habit.     -   4. Red-colored single flowers with white-colored centers and         narrow margins.     -   5. Good container and garden performance.

Plants of the new Carnation differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Carnation have smaller leaves than plants         of the female parent selection.     -   2. Plants of the new Carnation have larger flowers than plants         of the female parent selection.     -   3. Plants of the new Carnation and the female parent selection         differ in flower color as plants of the female parent selection         have pink-colored flowers.

Plants of the new Carnation differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Flowers of plants of the new Carnation have smaller petals         than flowers of plants of the male parent selection.     -   2. Plants of the new Carnation and the male parent selection         differ in flower color as plants of the male parent selection         have pink-colored flowers.

Plants of the new Carnation also can be compared to plants of Dianthus L. ‘Sunflor Olivia’, not patented. In side-by-side comparisons, plants of the new Carnation differ primarily from plants of ‘Sunflor Olivia’ in flower color as plants of ‘Sunflor Olivia’ have white-colored flowers with a narrow red-colored ring.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Carnation plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Carnation plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Hilbeaolswee’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the spring in 10.5-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial container Carnation production. During the production of the plants, day temperatures ranged from 12° C. to 16° C., night temperatures averaged 12° C. and light levels averaged 7,000 lux. Plants used for the photograph and description were three months old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
